bash - Linux Shell Curl Command -


i have problem using curl command: have download file site of "www.example.com:8000/get.php?username=xxxx&password=xxxx" form.

now happens this: if open link browser, if file exists, part of automatic download, if link not correct, nothing happens , displayed page white.
problem using command curl -o file.txt "www.example.com:8000/get.php?username=xxxx&password=xxxx", file generated me if link correct, downloading file correctly, link not right, generating 0 byte .txt file.

how can that, if not corrected link (and therefore there no file download), no file generated me?
